Could someone show me exactly how to create a non-blocking TCP/Stream socket? Thanks in advance. First, to make the initial socket creation/connection not block, you use: http://php.net/ini_set on that one socket connection timeout thingie in php.ini I can't remember right now. *THEN* after you have the socket up and running, you use: http://php.net/socket_set_block At least, that's the way I remember it from the last time I played this game... -- Some people have a gift link here.

You cannot do a non-blocking connect. -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Using a stream is much more flexible.

[PHP] non-blocking sockets + newbie compile question
1) socket_set_blocking()... what the devil's up with this? *I* get socket_set_blocking(): supplied resource is not a valid stream resource, which is obviously a lie, since I can connect to the server program and socket_recv and socket_send both work. I'm using PHP 4.3.1 (cgi) 2) I figured I'd compile the latest CVS snapshot, too, to see if maybe my non-blocking socket will work with that. I've done configure and make, but not make install. What do I do to get my nice new php without replacing the old one? -Josh -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
